## 4. Consensys / MetaMask (outreach — no public “add chain” PR)
|
|
|
|
**Contact:** https://consensys.io/contact/ , business@consensys.io; MetaMask: https://support.metamask.io , https://developers.metamask.io
|
|
|
|
**Repositories (reference only; Swaps/Bridge/on-ramp are Consensys-controlled):**
|
|
|
|
| Repo | Purpose |
|
|
|------|--------|
|
|
| **MetaMask Snaps** | Your Snap can already support Chain 138; no PR to “add chain” to native Swaps/Bridge |
|
|
| **Consensys** | Native Swaps, Bridge, Buy/Sell for Chain 138 require partnership/outreach; no public PR repo for “add network” to those products |
|
|
|
|
**Outreach package:** [metamask-integration/docs/CONSENSYS_OUTREACH_PACKAGE.md](../../metamask-integration/docs/CONSENSYS_OUTREACH_PACKAGE.md) — use for email/contact form. Await response before expecting technical PR steps.
|
|

|
|
## 5. Price Feed — MetaMask and All Wallets
|
|
|
|
**Master doc:** [PRICE_FEED_CHAIN138_METAMASK_AND_WALLETS.md](../04-configuration/PRICE_FEED_CHAIN138_METAMASK_AND_WALLETS.md) — single reference for adding Chain 138 USD prices to MetaMask and wallets.
|
|
|
|
---
|
|
|
|
## 6. CoinGecko / CoinMarketCap (submission, not PR)
|
|
|
|
**Submission (not GitHub PR):**
|
|
|
|
| Platform | URL / process |
|
|
|----------|----------------|
|
|
| **CoinGecko** | https://www.coingecko.com/en/coins/new — chain and token listing request |
|
|
| **CoinMarketCap** | Use CMC listing/submission process (DEX or token form) |
|
|
|
|
**Runbook:** [CMC_COINGECKO_SUBMISSION_RUNBOOK.md](../04-configuration/coingecko/CMC_COINGECKO_SUBMISSION_RUNBOOK.md) — export from report API (`/api/v1/report/coingecko`, `/api/v1/report/cmc`), then submit via platform forms. Chains 138 and 651940 may need to be supported by the platform first.
|
|
|
|
---
|
|
|
|
## 7. On-ramps and off-ramps (connect / add network)
|
|
|
|
Most on-ramp/off-ramp providers do not accept public PRs to “add a chain”; they use partner/API or internal chain lists. Use this list to **request** or **connect** Chain 138.
|
|
|
|
| Provider | How to add / connect Chain 138 | Repo / link (if any) |
|
|
|----------|--------------------------------|----------------------|
|
|
| **MoonPay** | Partner/API; request network support | https://www.moonpay.com/contact — no public chain-list PR repo |
|
|
| **Ramp Network** | Partner integration; request network | https://ramp.network/ — developer/partner contact |
|
|
| **Transak** | Partner; add network via dashboard or partner API | https://transak.com/ — partner/listing request |
|
|
| **Onramper** | API; check if they support custom RPC/chainId | https://onramper.com/ |
|
|
| **Banxa** | Partner integration | https://banxa.com/ |
|
|
| **Coinbase Pay / Onramp** | Partner; add supported networks via Coinbase | https://docs.cdp.coinbase.com/ |
|
|
| **MetaMask Buy (Consensys)** | Covered by Consensys outreach above | Same as §4 |
|
|
|
|
**Current path (no native 138):** Users buy on a supported chain (e.g. mainnet) via ramp → then bridge to Chain 138. Off-ramp: bridge 138→mainnet → sell on mainnet. See [MAINNET_LIQUIDITY_AND_RAMPS_PRIORITY.md](MAINNET_LIQUIDITY_AND_RAMPS_PRIORITY.md), [MAINNET_RAMP_USER_FLOWS.md](../04-configuration/MAINNET_RAMP_USER_FLOWS.md).
|
|
|
|
**Ramp API in repo:** `metamask-integration/src/ramps/` — `POST /ramps/on-ramp/session`, `POST /ramps/off-ramp/session`; set API keys (MOONPAY_API_KEY, RAMP_NETWORK_API_KEY, etc.) in .env.
